My invention relates to container closures and refers particularly to closuressuitable for use with containers made of paper, cardboard, fiber, wood and similarcomposition.

iOne'of the objects ofmy invention is a .device capable of being appliedto a container by means of prongs in such a manner that a practically complete closure'will be accomplished by means of a plurality of prongs carried by the device. v 7

Another object of my invention is a pronged device in which the prongs may be individually or in unison inserted within the sideof a container forming a; tight 010- i sure, the prongs being capable of removal and the device removed without destroying the container. Y

The above mentioned, and other valuable,

. attributes of my device will be evident upon a consideration of this specificationand its accompanying drawings. 7

One of the features of my device s the ease with which it may beefiectively employed as a closure.

he 0 erations of ada tation to a cco'ntainer consist in placing it over the open end 1 of the container, and pressing a plurality of tongues each carrying a prong, such pressure causing the prongs to enter theside of the container and retaining the closure upon the container.

These prongs may be inserted individually by pressing upon. the individual tongues, or they all may be inserted at once by forcing a band, or ring, downwardly over the angularly positioned tongues, thus forcing all of the prongs into the container side simultaneously, and inthe latter operationthe band, or ring, acts as a means formai'ntaining the prongs in their inserted pos tions.

It 1s frequently desirable to remove a container closure without destroying the con tainer in order to obtain access to the contents and to allow oi'tithe replacement of the closure. This is readily accomplished inmy deviceby withdrawing theprongsfrom 111- sertion within the container wall, which a].- 1, lows ofthe removal oi the closure and its replacement into closure position whende sired. I g7 While I have described herein certain definite forms of my device, it is evident that changes may be made within the scope of my invention.

The [particular form of the device of my Figure Tie a cross-section through the Figure 9 is a, cross-section through the invention shown in Figures 11 to 3, inclusive, 7

comprises an'annular metallic closure cover having a central portion 1O, the outer portion of which isbent upwardly at 11, trans- The outer flangeIport-ion 13 has a plurality of integral extended tongues. let, l4, in each of which a pointed prong 15 has been formed by stamping, orcutting, the two sides thereof and'inwardly bending the thus produced pointed prong. r

In operation the dev1ce is placed across the upper opening of the container 16, the

devicethen being-in the position shown in Figure 3, the tongue 14? and its prong 15 being in theposition shown in dotted lines, thus allowing the introduction otthe upper portion of the side17 of the container 16 to. be inserted within the Ushaped recess formed by the members 11, 12, and 13. The

tongues 14, Lt'are then pressed inwardly,

causing the prongs .15, 15.to enter the container wall 17. .It 'willlbejnoted, that atight jointure is thus formed between the closure and the container wall, the closure being maintained in position by the prongs 15, 15.

To remove the closure, the tongues 14,;1 t, are bent outwardly by any suitable means and in Figures 6 and 7-, illustrate a form of tongue, which allows of this withdrawal.

loo J In this tongue construction, the lower portion 18 of the tongue is bowed outwardly thus allowing the insertion of a suitable instrument between theltongne and the container wall.

In the modified form of the device of my invention shown in Figures 5 and 6, each tongue 14: has an extended integral prong 19, capable of being bent inwardly for purposes of insertion within the container wall 17.

In Figures 8 and 9, I show a means for clamping the prongs within the container walls, which 1s particularly adaptable in these cases in which the device is made of thin metal. In this construction, each tongue is recessed at the lower extremity 20 by rolling, or bending, the tongue outwardly and upwardly. A lug 2'l is formed by pressing the tongue metal outwardly at that point. A wire ring 22 placed around the device rests within the tongue recess and is prevented from upper movement by the lugs 21, 21. The wire ring 22 may be made of the proper size and forced downwardly into position, or a wire may be drawn around the device and the ends fastened togetherby any suitable means. It will be noted that if the closed ring, or band, is forced downwardly, it will cause all of the prongs to enter the container side simultaneously.

In Figure 10 I illustrate a form of my device in which the central member 23, extends over, and abuts upon, the upper edge of the side 17 and carries the tongues 14, 14 each having an extended prong 19.

It will be noted from the above that my device provides an inexpensive and effective means for closing a container, that is easily attached, that the attachment is of a firm character and that the closure thus formed is dust proof.

I do not limit myself to the particular size, shape, number, arrangement or material of parts as shown and described as these are given simply as a means for clearly doscribing my invention.

lVhat I claim is: V

1. In a container closure, in combination, a central member, a flange carried by the central member, a plurality of downwardly extended'tongues carried by the outer portion of the flange, a prong extending inwardly from each tongue and a closed ring capable of downward movement over the said tongues such movement forcing the tongues into the sides of a receptacle upon which the device is placed.

2. In a container closure, in combination,

a central member, a U-shaped flange carried by the central member, a plurality of downwardly extended tongues carried by the outer portion ofthe flange, a prong extending inwardly from each tongue and a closed ring capable of downward movement over the tongues such movement forcing the tongues into the sides of a receptacle upon which the device is placed.

3.
